Answer:
3x^2 - 3x + 9
Step-by-step explanation:
you combine like terms. so the only things you can subtract is 7 - -2 which is actually 7 + 2. hope this helped
Answer:
(3x² + 7) – (3x - 2)= 3(x²-x+3)
Step-by-step explanation:
3x² + 7- 3x - 2 -add 7 and 2 to get 9
3x²- 3x+9 -factor the common term which is 3

What is Area?Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. The area of a plane figure is the area that its perimeter encloses. The quantity of unit squares whcihh cover a closed figure's surface is its area.
We have, Radius of semicircle = 2 in
So, Area of semicircle = πr²/2
= 3.14/2 x 2/2 x 2 /2
= 1.57 x 1 x 1
= 1.57 mm²
So, the area of the semicircle is 1.57 mm².
Therefore, Radius = 1 in

If Catherine traveled 1,800 miles in 6 hours on her plane flight to her vacation destination, how fast was the plane traveling?
Answer:
So the plane drobe 1800 miles in 6 hours.
to find the time to plane was traveling per hour, we divide 1800 by 6 geting us with 300. THe plane traveled 300 miles per hour
Step-by-step explanation:
Answer:
300 mph
Step-by-step explanation:
[tex]Speed \: of \: plane \\ = \frac{distance}{time} \\ = \frac{1800}{6} \\ = 300 \: mph[/tex]
Thus plane was travelling at 300 miles per hour speed.

Three ballet dancers are positioned on stage. Mia is straight behind Jane and
directly left of Christine. If Jane and Mia are 3 meters apart, and Christine and Jane
are 5 meters apart, what is the distance between Mia and Christine?
Answer:3 m
Step-by-step explanation:
Given
Mia is 3 m behind Jane
Mia is left to the Christine
Distance between Mia and Christine is 5 m
Thus they form a right angles triangle shown in fig
So we can write
[tex]5^2=x^2+3^2[/tex]
Where x =distance between Mia and christine
[tex]x^2=25-16[/tex]
[tex]x^2=9[/tex]

You and two of your friends go to eat pizza together. There are two deals: 10% off of 1 pizza 30% off of 3 pizzas Do you want to each pay separately and get 10% off of your bill or do you want to split the bill 3 ways and get 30% off of 3 pizzas? Write a paragraph that convinces your teacher which one is the better deal. Show all of the math involved in your calculations.
Please help :(
Answer:
The first one is the better deal.
Step-by-step explanation:
The first one is the better deal =====
30% of 3 = 0.9
0.9 = 90
10% of 1 = 0.1
0.1 = 10
So the better deal would be 10% of 1
Which circle is the graph of the equation (x - 3)2 + (y + 4)2 = 9?
Circle A
Circle B
Circle C
Circle D
Answer:
a circle with center at (h, k) or (3, -4) and radius 3
Step-by-step explanation:
Next time, please share the answer choices.
(x - 3)^2 + (y + 4)^2 = 9 = 3^2
is a circle with center at (h, k) or (3, -4) and radius 3.
Which represents the inverse of the function f(x)=4x?
Answer:
[tex]h(x) = \frac{1}{4}x[/tex]
Step-by-step explanation:
Suppose h is the inverse of f then
f(x) = y ⇔ h(y) = x
f(x) = y ⇔ 4x = y ⇔ x = y/4
and since x = h(y) then h(y) = y/4
then we can write :
[tex]h(x) = \frac{x}{4}[/tex]

Which is a solution to 2x + 1 = 21?
Answer:
x = 10 is your answer
- Explain -
Step 1: subtract 1 from both sides (subtraction of equality)
which will give us:
2x = 21 - 1
which equals to
2x = 20
Step 2: Divide both sides by 2
which is
2x/2 = 20/2
2/2 = 1 and 20/2 = 10
Therefore the answer is x = 10

What is the exact circumference of a circle with a radius of 15 cm? 10πcm 15πcm 30πcm 60πcm WIIL GIVE BRAINLIEST
Answer:
(C) 30πcm
Step-by-step explanation:
In order to find circumference you use the formula C (circumference)=2(pi)(r) in which r is the radius. In this case, two and 15 are thirty so to find the circumference all you have is the equation 30 times pi centimeters is equal to the Circumference.
Answer:
37 pi
Step-by-step explanation:
The circumference of a circle is equal to pi times the diameter.
The formula for the circumference of a circle is C=pi d,and since d = 37 ,we know that C=37 pi.
37 pi =116.238928183,but pi is irrational and the decimal will never end.
Thus,the most exact way to express the circumference is 37 pi.

Option D
What value of a makes the equation true
Answer:
The correct answer is -2.
Step-by-step explanation:
it is -2 because if you replaced -2 with a you would have -2 minus 1.5 which is -0.5. -0.5 multiplied by 3 gets you -1.5.
Answer:
Step-by-step explanation:
3(a + 1.5) = -1.5
3a + 3*1.5 = -1.5
3a + 4.5 = -1.5
Subtract 4.5 from both sides
3a + 4.5 - 4.5 = -1.5 - 4.5
3a +0 = - 6.0
3a = - 6
Divide both sides by 3
3a/3 = -6/3
a = -2
